same symptoms on a ThinkPad X60: suspend will go through the motions, until it finally flashes the caps lock and num lock LEDs, does the "final" beep, but the hibernating LED keeps on blinking, and the machine is still running. ALT-SysRq-b will cause the machine to reboot, otherwise keyboard, screen are dead.
